Reply to "Alignment Specifications ?"

Robbie, you are correct. Alignment specs needed for narrow, hard-compound bias-ply tires are quite different from wide, low profile sticky compound radial tires. Plus, with wide, low profile radial tires it's been found in the last 44 years that extra camber improves stability more than extra toe-in, and tire wear is vastly diminished. Finally, the alignment settings you should use depends somewhat on how much city driving vs open highway running you do, and the tires you choose.

FWIW, there is nothing in the published alignment specs that I personally use for fast street driving with wide 50-profile radial tires on our '72. 6 degrees of theoretical front caster would be nice- '71 Corvettes used it but not without power steering! 4.5 degrees is more reasonable in a semi-stock Pantera and far easier to manually steer at low speeds. 2.6 degrees is all the factory parts will allow- one cannot get more front caster without machining the upper ball joints and/or using offset polyurethane a-arm bushings, or a custom upper a-arm. It's unfortunate the Pantera was introduced before radial tires were being cautiously offered to the public.
